MicroDyne Computer Systems Inc. (Ft. Lauderdale, Fla.)

In 1983, S-100 systems were still popular, and MicroDyne claimed that the MCS-100 was the only S-100 portable available at the time, although at least one other manufacturer (MicroStandard Technologies) offered it as an option. This makes the MCS-100 an interesting find for S-100 as well as portable collectors. One of the dual Z80A CPUs controlled the video.
